Because of our diverse applications, it is highly desirable that the candidate have knowledge and experience in a range of areas including machine learning, mathematical optimization including discrete, non-linear and stochastic programming; computational learning theory; and computational complexity. Applications include pattern recognition/classification and learning and prediction of adaptive signal behavior. A Ph.D. in applied mathematics, electrical engineering, computer engineering, or computer science is highly desired.

Digital Design: Design, implement, and verify complex, high clock rate digital circuits, including high speed mixed signal circuits, for EW applications. Our current focus is on programming the Xilinx Virtex family of FPGAs using VHDL, although Verlog experience is applicable.

MSEE in electrical engineering is desired.

RF & Microwave Analog Circuit Design: Design and instantiate RF/microwave circuits for high performance applications. Although we are not an IC design or chip fabrication house, we do have needs for microwave analog circuit designers to work with DSP specialists in a co-design process to reduce non-linear distortions in both receivers and transmitters. The position requires skill in IC design in one or more of the major analog and mixed signal function blocks of EW and Radar systems: up/down frequency conversion, ADC/DAC, filtering, and/or amplification. The position requires experience with industry standard EDA tools like Cadence or ADS. Since we are a research organization, the skill to create innovative analog design solutions is highly desired, however tempered by the need for reproducible and robust performance. Experience and skill with top-down design is desired.

Database Programming: The primary focus of the position is to program and implement custom databases as web-served applications. Currently the Branch is using MySQL on an Apache Server with PHP server side scripting. For “standard” database applications, like record/asset management, the position will also determine if commercially available packages will satisfy, or can be modified to satisfy, Branch requirements. The candidate will also learn the Branch’s current web-served accounting database, written in MySQL, with the expectation of making future enhancements. The position will provide helpdesk support to Branch personnel using the databases. The position will document all software development. Experience in database programming with MySQL is required. Experience with development of web-served applications is required.

Software Development: This is a broad category ranging from identifying and designing a software solution to coding.
